This part of IEC 60598 specifies requirements for fixed luminaires intended for use in water, or in contact with water, in, for example, the basins of swimming pools, fountains, paddling pools, and garden pools, and for use with electric light sources.

This document does not cover luminaires not in contact with water (e.g. mounted behind a glass panel which is separate from the luminaire) or hand-held or portable luminaires.
